Math Problem Statement
Rewrite cot^2(x)cos(x)/(csc(x)-1) as an expression that doesn’t include a fraction
Solution
We are given the expression:
Step 1: Rewrite in terms of sine and cosine
First, express and in terms of sine and cosine:
Now substitute these into the original expression:
Step 2: Simplify the numerator and denominator
